Overview
The Needle/Compact Pylon has a minimal footprint and Right Of Way (ROW) compared to the traditional steel lattice pylon. It is also faster to build. Prefabricated in spun concrete or bolt-together sections in steel, it can be assembled by a small team in less than a day, compared to the nine-people working for five days required for the original design.
By using spun concrete, it is possible to produce and install the total pylon in one piece. It takes a few hours to drill a hole, where after the pylon is directly embedded. This method has been used in the US for 345 kV and 500kV produced and installed by Valmont who is one of the market leaders in the United States.
The pylon arrives at the building site-read for installation. The pylon can be produced up to 150 feet/50 meters in one piece.
